瑜伽論記 1.296

1.296

初文中云謂由壽量極故而便致死者，總釋死義，莫問時非時死，但是捨命名壽量。極於其六中，基師解云：初三死，不明了識，離身正死。後三死，明了心識，未離身將死。

In the first passage, 'due to the exhaustion of the lifespan, death is incurred' generally explains the meaning of death: regardless of timely or untimely death, it is simply the relinquishment of life called the exhaustion of the lifespan. Among the six, Master Ji explains: The first three deaths pertain to unmanifest consciousness, which is actual death upon departing the body. The latter three deaths pertain to clear mental consciousness, when one is about to die before departing the body.
